Electric Accessories Layout 8 SJ-D30M SJ-D33M FUNCTIONS 1. ADJUSTABLE TEMPERATURE CONTROL (1) Temperature control of freezer Thermostat (senses freezer temperature) operates on ON/OFF switchover to control the compressor and cool air circulating fan , and allows the freezer temperature to keep at a suitable temperature. However adjust the freezer temp. control knob as follows depending upon the storing condition of foods. PURPOSE KNOB SETTING MAX(Coldest) For making ice rapidly or fast freezing. When restocking with fresh food. For normal freezing. MED For storing frozen food for a short period (up to one month). When frozen food or ice cream is not stored. MIN Figure F-1. (2) Temperature control of refrigerator Damper-thermostat senses temperature of the refrigerator and changes the opening angle of the damper automatically. However, as the Damper-thermostat has no function to switch on or off the compressor and fan motor, the freezer temperature control causes temperature in the refrigerator to vary to some extent. However, adjust the refrigerator temp. control knob as follows depending upon the cooling condition. PURPOSE KNOB SETTING MAX(Coldest) For keeping freshness of food longer. When the refrigerator does not provide sufficient cooling. For normal operation. MED When the refrigerator provides excessive cooling. MIN Figure F-2. NOTE: The refrigerator temperature is affected also by the freezer temperature. If the freezer temp. control knob is set at the position "MAX", the temperature tends to be lower than the following values, and if set at near the position "MIN", temperature tends to be higher. If the refrigerator is operated for a long time with the freezer temperature control sets the "MAX" position, foods stored in the refrigerator compartment may also freeze. When refrigerator temperature control sets to the "MAX", some foods stored may freeze. In this case adjust control set back to the "MED" position. When refrigerator temperature control sets to the "MAX", some foods stored in Fresh case may also become frozen. (3) Reference value of temperature SETTING OF FREEZER TEMP.

The values shown above refer to the measurement carried out center area and 1/3 of overall height from the bottom at each of the refrigerator and the freezer after machine has been operated at an ambient temperature of 30˚C with no food stored and the door closed until the temperature is stabilized. The values vary depending upon frequency of opening and closing the door, ambient temperature, amount of stored foods and manner of storing foods. 9 SJ-D30M SJ-D33M 2. DEFROSTING (1) No defrosting operation is necessary No defrosting operation is necessary. As this machine is so designed that a built-in evaporator cools air and a fan circulates cooled air, neither the freezer nor the refrigerator is frosted, though the evaporator is frosted. The frosted evaporator is defrosted automatically due to the function of defrosting timer and heater, requiring no defrosting operation. (2) Where is melted frost brought 1. Melted frost is brought into the evaporating pan at the back of the set and is evaporated here by the heat of compressor. 2. Be sure to use Evaporating pan as inserted so as to be level with the outer case. (3) The following circuit diagrams in the table show automatic defrosting function of the refrigerator with timer and defrost thermostat. Operation 1. Cooling (Normal) Electric diagram Defrost thermostat ON Compressor running Timer motor running Thermo. fuse Defrost heater TM Defrost thermostat (ON) COMP Compressor Timer contact Timer motor SOURCE Thermostat Description The integration timer integrates running time of the compressor. When it reaches cycle time of defrost timer, the timer contact is changed to start defrosting. Figure F-3. Defrost thermostat ON (Time 20 to 30 min.) Thermo. fuse Defrost heater TM Defrost thermostat (ON) COMP Compressor Timer motor stops Timer contact Thermostat SOURCE Compressor stops Timer motor 2. Defrosting The timer contact is changed to start defrosting, the timer motor stops, and power is supplied to the defrost heater. It takes about 20 to 30 min. to defrost. When little frosted, the defrosting takes little time. When much frosted, the defrosting takes much time. Figure F-4 . Defrost thermostat OFF Thermo. fuse Defrost heater TM Defrost thermostat (OFF) COMP Compressor Thermostat SOURCE Compressor stops Timer motor running Timer contact (Time approx. 5 min.) Timer motor 3. Drain When the defrost thermostat becomes OFF, the timer motor starts running. During the operation time (delay time of defrost time) defrosted water is drained outside the refrigerator. Figure F-5. Defrost thermostat OFF SOURCE Thermostat Compressor running Timer motor stops Timer contact Thermo. fuse Defrost heater TM Defrost thermostat (OFF) Figure F-6. 10 COMP Compressor (Time approx. 5 min.) Timer motor 4. Restart Timer contact is changed to cooling operation and the compressor starts running and the timer motor stops. Defrost thermostat contact becomes ON when it’s cooled. And the timer motor starts running. (Figure F-3.) SJ-D30M SJ-D33M (4) As a reference to determine the causes of trouble, malfunction and phenomena are described below. Refer to the following when repairing. 1. Disconnection of defrost heater As off-cycle defrosting is performed, the defrosting time is extremely prolonged. Each time defrosting is started, the freezer temperature rises and a portion of ice and stored foods are melted. 2. Melted thermo. fuse or opened-circuit due to the defect of defrost thermostat. When the above mentioned trouble occurs in cooling operation, the timer motor does not run, defrosting will not take place, and consequently freezing is caused. In the above mentioned condition, when the timer shaft is turned by hand to defrost, the timer motor runs during the operation time. However, the motor stops from the time when the contact is changed, and freezing causes. NOTE: As the thermo. fuse assembly is intended to prevent dangers, do not use it under shorted condition even for a short period. 3. DEW PREVENTION The hot pipe, namely D.P.-condenser, is arranged around the flange part of cabinet and the C-partition plate, preventing dew from being generated on the cabinet. NOTE: D.P.-condenser pipe may be felt hot if touched by hand while the compressor is in operation. If you are asked about this, please explain that the hot pipe serve to prevent the dew generation. Hot pipe Figure F-7 4. INSPECTION OF INITIAL STARTING (1) Inspection of cooling unit 1. Set the temperature control knob to "MAX" and check that the compressor starts to operate. 2. Depress the door switch to run the fan and check that cool air is blown out of the cold air outlet of the freezer and the refrigerator. 3. When the compressor does not work, check that the timer is not set to "defrost" position. 4 It takes about an hour and a half or two hours to put food in the refrigerator after starting operation. NOTE: After return the temperature control knob to "MED" position. When the refrigerator is operated initially after installed, the compressor may vibrate excessively for 1 to 2 min. However, vibration becomes normal if it is continuously operated. (2) Inspection of defrost device Operate the refrigerator for 20 to 30 min. and then check the defrost device in the following procedures : Allow 5 min. to restart the compressor since immediate starting after stopping will cause unsmooth operation. 1. Turn the timer shaft clockwise with a screw driver. At this time, make certains the timer clinks and the compressor stops. 2. After more than 5 min., turn the shaft further to operate. Make certain cooling operation is started again. 11 SJ-D30M SJ-D33M ASSEMBLING PROCEDURES OF MAIN PARTS AND CAUTIONS CAUTION: DISCONNECT THE UNIT FROM THE POWER SUPPLY BEFORE ANY REPAIRING. 1.
